There is no difference between hemorrhoids and piles. They are two terms used to describe the same medical condition, which is the swelling and inflammation of the veins in the lower rectum and anus. Hemorrhoids or piles can cause discomfort, pain, itching, and bleeding during bowel movements. They are common and usually not serious, but they can be bothersome and require medical attention in severe cases. Treatment options range from lifestyle changes, such as increasing fiber intake and staying hydrated, to medications and surgical procedures.
